Filed: 1919-12-18
Abstract: 164,779. British Thomson - Houston Co., Ltd., and Whitaker, F. P. Dec. 18, 1919. Wendings.-In a dynamo-electric machine having a lap or wave-wound duplex or multiplex parallel winding, the brushes on any one brusharm are divided into as many groups as there are separate windings, the groups of brushes being progressively displaced from each other in a circumferential direction by the width of a commutator segment. Fig. 2 shows the arrangement of the brushes in three groups 3, 4, 5 for a triplexwinding. In a modification applicable to a commutator that is fully equalized, the brushes of either polarity are unequally spaced around the commutator, individual brush-arms being displaced from the theoretical spacing by the width of one commutator segment in the case of a duplex winding and by the widths of one and two segments in the case of a triplex winding, as shown in Fig. 3. Fig. 4 is a diagram of a wavewound duplex winding showing the brushes 3, 4 and equalizer connections 8, 9. Specification 25386/04 is referred to.

Title: Improvements in or relating to the manufacture of steel members for reinforcing concrete
IPC: B21H3/00
Filed: 1954-11-05
Abstract: 793,305. Making reinforcing rods for concrete. WESTFALENHUTTE AKT.-GES. Nov. 5, 1954 [Nov. 7, 1953; Aug. 23, 1954; Sept. 22, 1954], No. 32127/54. Classes 83 (2) and 83 (4). Soft steel bars for reinforcing concrete are provided with transverse ribs by cold-rolling them until the reduction of size of the bar between ribs is more than 30 per cent, preferably 30 to 40 per cent, and the bars are then annealed at temperatures between 450 C. and 600 C. for a sufficient period to restore the toughness values of the depressed portions without substantial loss of elastic limit and tensile strength. The bars may be rectangular or square or a round bar may be cold-rolled at the annealing temperature to give an oval section as shown in Fig. 2 or an oval bar may be rolled to give a round section with both transverse and longitudinal ribs as shown in Fig. 6. The annealing time required is between 15 and 60 minutes. The fillet areas between the ribs and the depressed portions are given a sharp radius so that during the annealing treatment these areas are softened and can readily change their shape so as to avoid stress concentration points. In a modification, the same effect as cold-rolling is obtained by twisting bars with longitudinal ribs, the bars being twisted to such an extent that the pitch of the spirals is less than six times the diameter of the member so that the adhesion to concrete is improved and also the toughness values. The number of longutidnal ribs is chosen according to the pitch so that the rib spacing after the greatest twisting amounts to about 0.7 times the diameter. For example, with a pitch of about three diameters, four ribs are required and with a pitch of about four diameters, six ribs are required. Soft steel of which the nitrogen content has been decreased, for example, by oxygen enrichment of the blowing gas, may be used. Specification 728,636 is referred to.

Title: Improvements relating to variable speed gearing
IPC: F16H37/00
Filed: 1933-11-18
Abstract: 427,431. Variable speed gearing. ANDREWS, E. S., 329, High Holborn, London. (Weskenson Corporation ; Providence, Rhode Island, U.S.A.) Nov. 18, 1933, No. 32224. [Class 80 (ii)] Variable-speed gearing includes a mechanism for converting a uniform rotary motion into a variable cyclically varying rotary motion which comprises a member or members such as racks 40, 41, Figs. 4, 5 and 7, with standard gear teeth mounted upon a rotating driving-plate 37 and which are moved relatively to the plate to maintain standard pitch line contact with a pinion member 42 on a shaft 61 supported on a adjustable arm 60, and means for varying the position of the pinion 42 to adjust its effective distance from the centre of rotation of the rotating plate 37 to vary the speed ratio of the gearing. Periodic movement of the racks 40, 41, to keep in engagement with the pinion 42 on rotation of the plate 37 is effected by a cam plate 56 which is supported in guides in the plate 37 and which has a slot 58 in which a roller 59 on the shaft 61 of the pinion 42 engages, thus producing periodic motion of the cam plate to and from the centre of the plate 37, which motion is transmitted through a slot 57 and roller 55 to a rack 54 and then through gearing 52, 51, 49, 53, 50, to secondary racks 47, 48, and 45, 46, which are attached to the main racks 40 and 41. The cyclically varying speed obtained from the pinion 42 by uniform rotation of the rack plate 37 follows a simple harmonic law and Figs. 1 and 2 show the combination of two such speed mechanisms by a differential to obtain an approximately uniform speed. A drive shaft 20 drives similar rack plate mechanisms 37 and 32 at a uniform speed through gearing 128, 30, 31, 33, shaft 34, and gearing 35, 36. These rack plate mechanisms are arranged 90‹ out of phase and the cyclically varying components obtained are transmitted by gears 43 and 44 to differential gears 28 and 29 respectively, an approximately uniform resultant speed being obtained of the shaft 26, to which the spider 27 is attached, which speed is variable by variation of the position of two pinions 42. The speed of the shaft 26 can be further combined through an epicyclic gear 21, 22, 23, 25 with that of the shaft 20 to give a variation of speed of a driven shaft 24 from forward to zero and zero to reverse. The resultant speed of the shaft 26 obtained by the mechanism shown is not quite uniform and a compensating mechanism, comprising cams 65 and 66 on the shaft 34 for the two mechanisms 37 and 32 respectively imparting a periodic oscillating movement through linkages 70, 71 to the arms 60 carrying the pinions 42, may be employed to give a more uniform resultant speed.

Patent GB-728702-A (GB)
Title: Process for the production of amines
Filed: 1952-12-30
Abstract: Amines are produced by mixing an aliphatic or cycloaliphatic aldehyde with ammonia or a primary or secondary amine at a temperature below 0 DEG  C. and thereafter hydrogenating the mixture in the liquid phase at elevated temperature and pressure.  The hydrogenation is preferably carried out in the presence of a hydrogenation catalyst, such as a catalyst containing cobalt or nickel.  The aldehyde is preferably diluted with a low boiling solvent such as an alcohol or a hydrocarbon.  The process may be carried out batchwise or continuously.  Aliphatic and cycloaliphatic aldehydes of any kind may be used, e.g. unsaturated aldehydes, hydroxyaldehydes and dialdehydes.  In the examples: (a) propionaldehyde mixed with methanol is treated with ammonia at - 15 DEG  C.; a nickel catalyst is added and hydrogen is then introduced under pressure; the mixture is heated to give propylamine; (b) an Oxo synthesis product containing 62 per cent of C7 aldehyde and 38 per cent of C6 hydrocarbon is subjected to the process of (a) to give primary C7 amine and diheptylamine; (c) methyl ethyl acrolein is similarly treated to give 2-methyl-pentylamine and some propylamine; (d) propionic aldol is similarly treated to give hexanolamine and propylamine; (e) propionaldehyde is treated as in (a), except that propylamine is used instead of ammonia, to give dipropylamine; (f) butyraldehyde mixed with methanol is cooled to - 10 DEG  C. and treated with ammonia and then hydrogenated at elevated temperature and pressure to give a mixture of primary and secondary butylamine; (g) tricyclodecane methyl aldehyde, which is prepared from dicyclopentadiene by the Oxo synthesis, is treated with ammonia at - 5 DEG  C. and subsequently hydrogenated to give tricyclodecanemethylamine; and (h) camphene aldehyde, produced from camphene by the Oxo synthesis, is similarly treated to give camphene methylamine.
